MAJOR A. BAN OROFT, OF BLUNT, DAKOTA TERRITORY, ASSIGNOR OF ONE-PRINTING.,

SPECIFICATION 'forming part-of Letters Patent/No. 351,618, dated October26, 1886.

Application filed March 2G, 1886. Serial No. 106.687. (No mode'.)

To all whom t may concern,.-

Beitknown that I, MAJOR A. BANonoFT, a citizen of theUnited States,residing at Bl u nt,in the county of Hughesand Territory of Dakota,haveinvented certain new and useful Improvements in Printing, of whichthe following isa speciiication, reference Vbeing had therein to theaccompanying drawings.

My invention relates to an improvement in to the art of printing,whereby a divided print may be obtained i'rom a solid printing-thee, asan electrotype or wood-cut, the intermediate space to'be afterwardfilled by an impression from another form, giving the finished print r 5the appearance ot' an impression of' greater superficial area than thearea of said printingface. -f

The nature of my invention will be clearly understood from the followingdescription and 2o the accompanying drawings; Figure l ofthe drawingsrepresents atympa bearing an impression of a form to be printed from,the dotted lines showing how the tympan is to be cut for the firstimpression andv the gage-pins in position. Fig. 2 shows the tympanprepared for the iirstimpression. Fig. 3 represents a frisket on whichis an impression of the form, the portion to be removed being shown indotted lines. Fig. 4shows the frisket 3o prepared for thei'irstimpression. Figs. 5 and 6 illustrate the preparation of the tympanfor the second impression. Figs. 7 and 8 illustrate the preparation ofthe frisket for the second impression. Fig. 9 shows the product of therst and second impressions. 'Fig. 10

shows the completed print, the blank space left between the first andsecond impressions having been filled by a subsequent impression fromanother form; and Figs. lland 12 rep- 4o resent impressions from theform, the latter 'ligure showing the'print separated on the line a: x,Fig. 1l, none ofthat part of the form used to make the first impressionhaving been employed to make the second impression. Figs. 13 and 14represent the tympan and frisket prepared for an impression from anotherform,

to ll the blank space between the divided iin-- pressions of the cut, asseen-in Fig. 10.

In the explanation of my invention it is assumed that the form to beprinted from is a cut representing a two-story building,from which it isdesired to obtain a print representing a three-,story building withoutin any manner mutilating the cut,and that the form is placed in properposition on any ordinaryjob-printv ing press.

' In carrying ont my invention I first take an impression of the form onthe tympan A ofthe press, as shown at B, Fig. l. I then attach a sheetof heavy paper to the grippers C ot the 6o press to form a l'risket, D,on which, also, I take an impression of the form, as shown in Fig. 3',alter which I cut out that part of the irisket overlying the portion ofthe form fromv which I wish to take the first impression, as shown at Ein Fig. 3, and then cnt out that portion of the tympan underlying thatportion ofthei'risketcovering the remaining portion of the form, asshown at F in Fig. 2. Vhenpthese parts of the press are thus prepared, Iplace a 7o sheet oi'pap'erto be printed on the tympan, resting its edgesagainst the gage-pins G, and take an impression.

It will be understood4 that only so much of the form as underlies thecut out part of the frisket will print on the paper, the frisketreceiving the impression from the other part ofthe form. as shown at H,Fig. 4, and that, by reason of the tympan having been cut out,

as at F, Fig. 2, thispartIIof the t'risket will not 8o V he pressed sohard upon the paper being printed as to mar its surface, as would be thecase if the paper were not allowed to yield.

For the second impression a new tympan` sheet isprovided. An impressionof the form 8 5 is` taken upon it, as before, and the gage-pins G arelowered (or the form is raised) to such position as will give t-hedesired space between the prints ,produced by the tirst and secondimpressions, this location of the pins be- 9o ing shown in full lines inFigs. 5 and 6. An impression is then taken on a new frisket, as seen inFig. 7, and the portion necessary to be printed is cut out, as at E,Fig. 8.

1 It will be observed that in the illustration 95 here given the frisketis so cut as to includea portion of that part of the form which had beenpreviously printed from, in order to give a symmetrical appearance tothe iinished print. When the frisket is thus prepared,the tympan roo iscut out according to the directions above given, as shown atk F, Fig. 6.The sheets bearing the first impressions are then again run through thepress, the product of the two impressions being a divided print, such asis shown in Fig. 9.

The third impression, to fill the blank space between the first andsecond impressions and complete the representation of a three-storybuilding, may be had from another form, as shown in Fig. 10, which formis simply a single line of type with a piece of rule at each end andside in such position as to register with and complete the outlines ofthe impressions representing the building. For printing from this formthe frisket is cut out, as shown at It] in Fig. 14, and thetympan isent, as shown at F F in Fig. 13, leaving an uncut strip between the twocuts in the tympan, which strip is intended to underlie the cut part Eofthe frisket.

It is evident that the print may be divided on any given line, as x x,Fig, 11, and a divided pri nt-such as shownin Fig. 12-be producedwithout at the second impression in cluding any portion of that part ofthe t'orm printed from at the first impression.

By 'the method of printing above set forth divided prints can beobtained from letters as well as from ents.

I am aware of United States Patents No. 84,225. dated November 17, 1868,and No. 164,647, dated January 22, 1875, and make no claim to theinventions therein shown and described.

In another application, tiled by me o'n the lthday of December, 1885,Serial No. 185,940, the following claims are now pending and in processof adjudication, to wit:

1. The combination, with a form of type placed on the bed of aprinting-press, of the frisket, the portions which overlie the part ofthe form from which it is desired to take an impression being cut out,and a tympan having the portions which underlie the part ofthe frisketcovering the part of the form not to be printed from cut out,substantially as described.

1). As an improvementin the art of printing, the method herein describedof taking an impression from certain portions of an unbroken form,consisting in cutting out those parts of the frisket which overlie thoseparts of the form from which an impression is t'obe taken, and removingthose parts o1- the tyml'ian-shect which underlie the part of thefrisket covering the part of the form not to be printed from, thenapplying paper to the frisk et and tympan so prepared and taking animpression, substantially as described.7

Having thus described my invention,what I claim, and desire to secure byLetters Patent, 1s-

1. The improvement in the art of printing hereinbefore set forth,consisting, first, in entting ont that portion of the frisket whichoverlies the part of the form from which the first impression is to betaken, and cutting ont so much of the tympan as underlies the part ot'the frisket covering the remainder ot' the form, and taking animpression on a sheet of paper; secondly, in arranging the frisket tocover so much of that part ot' the form first printed from as is notneeded for the second impression, cutting out the tympan in the mannerindicated above, gaging the paper in proper relation to the form, andtaking the second impression; and, finally, in filling the space leftbetween the two impressions with an iinpression from another f'orm.

2. An improvement in the art of' printing. consisting, first, in cuttingout thatportion ot' the frisket which overlies the part of the form fromwhich the first impression is to be taken, and cutting out so much ofthetympan as underlics the part of the frisket covering the remainder oftheiorm, and taking an impression on a sheet of paper; secondly, inarranging the frisket so as to eovera portion ot' that part of' the formfirst printed from, cutting-ont the tympan as indicated above, gagng thepaper lower down on the tympan, and taking the second impression; and,finally, in filling the space left between the two impressions with animpression from another form.

In testimony whereof I afiix my signature in presence of two witnesses.
